中文摘要 | 目前國內公共圖書館網路規劃的方式是採取一個集中作業的中心,各分館或鄉鎮圖書館以不同速率的專線連入指定中心,再由這個中心連向所屬的台灣學術網路區網中心或縣網中心進入網際網路領域。傳統專線的運作方式在費用上與連線距離有關,距離越遠費用越高造成圖書館經營上的相當大的負擔。虛擬私有網路(VPN, Virtual Private Network) 的運作方式基本上則是以透過現有的公眾網路透過適當的軟體技術,模擬成私有網路運作方式目的,除了可以節省通信經費外,透過虛擬私有網路建區分服務及保障網路服務品質 (QoS) ,可以補足現行網際網路在通信控制上的缺失,本文旨在介紹虛擬私有網路的特性及基本概念,在未來公共圖書館網際網路的作業規劃上可以加以考量。 |
英文摘要 | The paper is to introduce the concept of VPN (Virtual private network) briefly. Basically, virtual private network emulates leased lines and routed networks by software over public network, such as Internet. VPN can reduce overhead of dedicated lines to establish private connection with remote branches and offices. However, most of public library networks were connected directly by different kinds of traditional leased lines at the moment, so they have to endure high cost on communication for leased lines and low quality without better quality of services. On the other hand, QoS (Quality of Services) has become one of most important issues for Internet services. It is very important for public libraries network planning to find out how to improve Internet services in public libraries in near future. PN probably will be one of best solutions on this issue. |
